Types and Application Fields of Micro DC Motors

Motors can generally be divided into 13 categories: DC motors, AC motors, self angle motors, stepper motors, rotary transformers, shaft angle encoders, AC DC dual purpose motors, speed generators, inductosyn, linear motors, piezoelectric motors, motor units, and other special types of motors.

Micro motors are small in size, capacity, and output power typically below hundreds of watts, as well as motors with special performance and environmental requirements. Commonly used in control systems to detect, calculate, amplify, execute, or convert electromechanical signals or energy, or to drive mechanical loads, it can also be used as an AC or DC power source for equipment. Micro motors are used in various fields such as disk drives, copiers, CNC machine tools, and robots.

Motor characteristics

The motor is a reversible synchronous motor composed of a permanent magnet synchronous motor and a built-in gearbox. It has the advantages of high torque, low noise, small size, light weight, convenient use, and constant speed operation. It can also be paired with various gearboxes to achieve the goal of changing output speed and torque.

Classification of motor structures

Electromagnetic type: The basic composition is similar to that of an ordinary motor, including components such as stator, rotor, armature winding, and brush, but the structure is particularly compact.

Combination: There are two common types: combinations of various micro motors mentioned above; The combination of micro motors and electronic circuits. For example, the combination of DC motors and sensors, the combination of X-direction and Y-direction linear motors, etc.

3. Non electromagnetic type: The external structure is the same as electromagnetic type, such as rotating products made into cylindrical shapes and straight products made into square shapes, but the internal structure varies greatly due to their different working principles.

Application scope

All low-power, constant speed, and high torque equipment such as food machinery, textile machinery, medical equipment, intelligent doors and windows, monitor heads, advertising light boxes, household appliances, air conditioning blades, actuator control, etc.

application area 

1. The driving field cooperation without special control requirements is the power source of the moving mechanical load.

2. Audio and video equipment. For example, in a cassette recorder, the micro electric motor is not only a key component of the magnetic drum component, but also an important component for its main shaft drive, automatic loading of the receiving and supplying tapes and cassette tapes, and tape tension control.

3. Office automation equipment, computer external equipment, and industrial automation equipment. Micro motors are used in various fields such as disk drives, copiers, CNC machine tools, and robots.
